Boy or Girl?

The Chinese Gender Prediction chart (it's based on your lunar age or something reliable like that...) says:
IT'S A BOY!

THIS nifty gender prediction test guesses:
IT'S A GIRL!
You have a 35% chance of having a boy.
And you have a 64% chance of having a girl.
(hmmm... 64+35=99 There is a 1% chance my child will be a hippopotomus.)And Here's Why...
You are carrying the extra weight out front, so it's a boy.
The hair on your legs is not growing any faster during your preganacy, so it's a girl.
Boys are carried low. You are going to have a boy.
Sleeping in a bed with your pillow to the south indicates that you will be having a girl.
Your feet are not colder than they were before pregnancy. You are having a girl.
Dad-to-be hasn't been gaining weight along with Mom-to-be, so it will be a girl.
The maternal grandmother doesn't have gray hair (dyed or natural), so a girl will be born.
You had morning sickness early in pregnancy, so you are expecting a girl.
You are looking particularly good during pregnancy. Therefore, it must be a boy, because girls steal their mother's looks.
Your chest development has been quite dramatic during pregnancy. You should expect a girl.
Since the sum of the mother's age at conception and the number of the month of conception is even, it will be a boy.
You have a craving for salty or sour foods, which means that it is a boy.
You have been craving fruits, so it is a girl.
Your baby's heart rate is 140 or more beats per minute, so it's a girl.

A facebook poll of friends and family's guesses had an overwhelming response of:
IT'S A BOY!

Daddy thinks he's figured it out that:
IT'S A GIRL!

...But Mama still thinks:
IT'S A BOY!

I guess none of these are terribly reliable sources... so we will just have to hold on. The sonogram in a few weeks should shed some light on the subject... if not? Well we will know for sure on or around Dec 22, 2011 (Baby P's Birthday!).
What's your guess?
